Do I need to upgrade to Windows 11? | IT Support for Dental Practices

With the October 2025 deadline for Windows 10 support behind us, it's understandable if there's a sense of urgency.

If your business is still using Windows 10 on some or all of its machines, the first thing to know is this: take a deep breath. The sky will not fall in. Your computers will still turn on and your business will continue to operate.

This isn't a hard stop, but it is a critical turning point. For anyone yet to make the switch, the immediate priority now shifts from just hitting the date to having a clear, documented plan in place. From a compliance perspective, demonstrating that you are actively managing the transition is just as important as the transition itself. This is a gentle reminder that the time to finalise that plan is now.

A quick refresher: why should you upgrade to Windows 11?

It's easy to be cynical and assume this is just a way for Microsoft to drive sales. While there's a commercial reality, the core reasons are rooted in technology and security. Supporting old operating systems is incredibly complex, and the digital landscape has changed. Modern security requires modern hardware.

This is why some older machines won't support Windows 11. The requirements, like the need for a TPM (Trusted Platform Module) 2.0 chip, are not arbitrary. This specific piece of hardware is fundamental to enabling the high-level encryption that protects your data. An OS that can't leverage these tools is a risk in today's world.

Understanding the practical risks

What does staying on Windows 10 past the deadline mean in practice? Once Microsoft support ends, so do the security patches. Your vulnerability to cyber-attacks increases significantly for every machine that remains on the old system. The consequences of a breach go far beyond technical headaches:

Regulatory scrutiny: authorities like the ICO take a dim view of organisations that fail to mitigate known risks. A documented upgrade plan demonstrates due diligence under regulations like GDPR.
Insurance and liability: your cyber insurance policy likely requires you to maintain patched systems. If you have a plan in place to move to a supported OS, you are in a much stronger position should you need to make a claim.
Reputational damage: a data breach can damage patient trust. Being able to show you were actively working to secure your systems can help manage the fallout.

Assessing your remaining systems

The good news is that not every machine will need to be replaced. To finalise your plan, you need a clear picture of what's left to do. For a wide-scale view, a remote PowerShell script like Microsoft's official Hardware Readiness Script can assess any remaining machines; for individual machines, the PC Health Check app gives a definitive answer. If you're a Dental IT customer, our monitoring has already analysed every machine on your network for Windows 11 readiness.

Navigating the final hurdles

The upgrade process is more than just the OS. Your plan should account for the entire ecosystem:

Specialised software: the dental market relies on specific imaging and X-ray software. Have you confirmed with your vendors that they are compatible with Windows 11?
Legacy applications: older versions of software, like Microsoft Office 2013 or earlier, may not install properly. Your plan should budget for any necessary new software licences.
Peripherals and configuration: remember to allocate time for reinstalling software, printers, scanners, and other peripherals on each upgraded workstation.

Finishing strong: an opportunity to modernise

Even in this final phase, try to see this as an opportunity. As you upgrade these last few machines, think strategically. Is that old tower being replaced by the right tool for the job? Could a modern all-in-one improve a workspace? This is your chance to ensure every piece of hardware is perfectly aligned with your business goals for the years ahead. See our IT refresh service.
